K4RCU3, K5RCU and K5RCU2
DTMF Receiver/ABR Tone Detector Unit
System:
DK40i Base KSU
Circuits per PCB:
K4RCU3: four DTMF receivers and four ABR busy tone detectors
K5RCU, K5RCU2: five DTMF receivers and five ABR busy tone detectors.
Interfaces with:
automatic busy redial (ABR)
interprets DTMF tones
DISA, DID, Tie lines
built-in auto attendant
Older Version(s):
K4RCU (not compatible with DK40i)
K4RCU3 or K5RCU (compatible with DK16 and DK40i
The K4RCU3, K5RCU or K5RCU2 must be installed to recognize Dual-Tone Multi-Frequency
(DTMF) tones generated by a standard telephone (or any other device connected to a standard
telephone circuit) and to enable ABR to operate. The K5RCU2 is the same as the K5RCU, except
that it has jumper settings for A law and Mu law, which makes it applicable to more countries.

Configuration

The K4RCU3, K5RCU, or K5RCU2 does not have to be configured for operation. If built-in auto
attendant is required, see auto attendant KKYS installation.

K4RCU, K5RCU or K5RCU2 Installation

1. Make sure that the power supply switch is OFF.
2. Make sure SW1 is set for Mu law if installing K5RCU2. The jumper must be set for Mu law in
the U.S. and Canada.
3. Making sure that the component side of the K4RCU3, K5RCU or K5RCU2 is face down
(toward the power supply), plug the K4RCU3, K5RCU P602A and P602B female connectors
into the P2A and P2B (K4RCU3, K5RCU or K5RCU2) connectors on the motherboard. See
Figure 3-15.

K4RCU, K5RCU or K5RCU2 Programming

Program 03: Enter code 92 for Slot 00 if K4RCU3 is installed or Code 98 with K5RCU or
K5RCU2.
Program 12: Sets K4RCU3, K5RCU or K5RCU2 release time.
Program 15: Sets K4RCU3, K5RCU or K5RCU2 operation after CO line flash. Assigns DTMF/
Dial Pulse dialing, DISA, and additional attributes to each line.
